To all whom it may concern:

Be it known that we, GUSTAV Eonorr and HARRY P. BENN'ER, citizens of the United States, residing in the city of Independence,

5 county of Montgomery, and State of Kansas, have invented certain new and useful Improvements in Hydrocarbon-Oil Treat ment, of which the following is a specification.

Our invention relates to a process for the refining of hydrocarbon oils of the character resulting from the distillation of crude petroleum oils, pressure distillation, of-heavy oils, shale, coal, peat and lignitic oils, or the like.

The feature of novelty in our process lies in the treatment of hydrocarbon oils to pro-\ duce sweet odored water-white 1i 'ht oils.

'ess, whlch 1s, however, only illustrative of therefrom by means of an acid an a com minuted solid material. Among the salient objects of our invention are, to provide a process for the production of water-white light oils; to provide a process for the refining of hydrocarbon oils; to produce sweet odored, water-white gasolene and kerosene in one operation; to provide a process in which a minimum amount of acid .is required comparative to the comminuted solid material; to-provide a process in which a liquid and a solid comminuted material are utilized to produce in the refining of hydrocarbon oils to produce marketable light oils therefrom; to provide a process in which an acid and coinminuted solid material such as fullers earth is utilized to refine hydrocarbon oils to produce water-white, sweet odored light oils therefrom; to provide a process in which hydrochloric acid, or the like, and fullers earth, or the like, are

4 placed in the body of a hydrocarbon liquid to be refined to water-white products. An illustrative test of process was to treat a cracked pressure distillate of Baum.

resinous forming properties, unlike the usual cracked gasolene and kerosene which uponstanding in the sun or other light source form resinlike bodies which have explosive properties. The "gasolene and kerosene produced by this process is stable as to color, odor and non-resin forming properties after standing in the sunlight for periods of time.

ture is overcome by this process.

As one method .of carrying out our procmany-others, we have successfully charged a container-with 1,000 cc. of pressure distillate oil, with which I have mixed 500 cc. of fullers earth and 50 cc. of hydrochloric acid. The specific oil whichlusd had-a Baum gravity of 45.0. The oil in the presence of the fullers earth and hydrochloric acid was subjected to distillation. The oil treated had aninitial boiling point of 122 F., with 90% thereof distilling at 530 F. The color of the oil before distillation was a yellowish brown and in distilling the oil We selected, three hours and seven minutes was required, the distillation range of the oil being 408 F.

The distillation of the product resulted in the formation of 37 thereof as gasoline, of a gravity of 58.4. This gasoline had an initial boiling point of 125 F. and an end point of 440 F. In 5% fractions, the first 5% went over at 158 F., while the final fraction that was distilled, same being the 93rd per cent thereof. went over at 440.

The kerosene fraction recovered was 29 and of a gravity of 40.2. It had an initial'boiling point of 290 F., with an end a point of 558 F.

In both the gasoline fraction and the kerosene fraction, the color both before and after distillation was water white.

We claim as our invention:

1. A process of refining cracked petroleum pils .consistiln in distilling said oils while subjected to t e'- action of hydrochloric acid and comminuted fullers earth.

Q 2. A process of refining cracked petroleum .5 oils consisting in distilling said oils while subjected to the action of an acid and comminuted fullers earth.

3. A step in the process of refinin oils which comprises subjecting crack petroleum oil while in the presence of hydro- 10 chloric acid and comminuted earthy material to a distillation temperature.
